Starting LifeKeeper

All LifeKeeper software is installed in the directory /opt/LifeKeeper.

When you have completed all of the verification tasks, you are ready to start LifeKeeper on both servers. This section provides information for starting the LifeKeeper server daemon processes. The LifeKeeper GUI application is launched using a separate command and is described in Configuring the LifeKeeper GUI. LifeKeeper provides a command line interface that starts and stops the LifeKeeper daemon processes. These daemon processes must be running before you start the LifeKeeper GUI.

Starting LifeKeeper Server Processes

!When LifeKeeper starts and establishes communication with the other servers in a cluster, it will not allow data replication (DataKeeper) resources to come in-service (manual or automatic) until communication is established with all servers in the cluster. The data replication resources will be marked OSF if an attempt is made to in-service them before communication is established with all servers. (Please refer to the system’s log files for additional information.)

If LifeKeeper is not currently running on your system, type the following command on all servers. The lkadmin privilege is required to run this command.

/opt/LifeKeeper/bin/lkcli start

When executing this command, the LifeKeeper service will be started and LifeKeeper will be set to start automatically at system startup.

Following the delay of a few seconds, an informational message is displayed.

*Note: If you receive an error message referencing the LifeKeeper Distribution Enabling Package when you start LifeKeeper, you should install / re-install the LifeKeeper Installation Image File.

See LifeKeeper Command Line Interface (LKCLI) for details on the lkcli command.
